The extent of Δ3(E)-unsaturation in GlcCer of
F. graminearum varies depending on the growth temperature.
A, TMS-FAMEs were derived from GlcCer of F. graminearum
grown at 18, 28, and 30 °C and analyzed by GLC. FID, flame
ionization detector. B, relative amounts of
18:13E in fatty acids of GlcCer and of 18:3 in
total C18 fatty acids. The level of
Δ3(E)-unsaturation in GlcCer decreased significantly when
F. graminearum was grown at temperatures above 28 °C. Data were
obtained from at least two independent experiments.
